Description

A kind of tobacco topping machine

Technical field

The invention provides a kind of tobacco topping machine, belong to agricultural machinery technological field.

Background technology

Tobacco is the important economic crops of China, and in China, southern and northern cultivated area is large, high financial profit, but tobacco is in process of growth, in order to improve the quality of tobacco leaf, control its growth, when tobacco growth reach a certain height, when blade quantity is determined, need tobacco to pinch, namely pinch head, suppress its longitudinal growth, make nutrient be transported to blade, improve leaf quality.

Current tobacco is pinched and is adopted artificial hand to pinch or with scissors scissors terminal bud, the muscle power of people is always limited, and efficiency is low.

Summary of the invention

The object of this invention is to provide a kind of tobacco topping machine, adopt tractor vehicular, the disc cutter that mounted in pairs is obliquely installed rotates under the drive of hydraulic motor, and the terminal bud of cut-out tobacco, once can complete a line or two row are pinched, and operating efficiency is high.

Its technical scheme is.

Comprise tractor, vertical lift oil cylinder, horizontal telescoping oil cylinder and cutter sweep, vertical lift oil cylinder one end is fixed in the frame of tractor setting, the other end connects with horizontal telescoping oil cylinder, the cutting position of vertical lift oil cylinder telescopic adjustment disc cutter in the vertical direction on (namely longitudinally), the cutting position of horizontal extension oil telescopic adjustment disc cutter in the horizontal direction in (i.e. transverse direction), due to tobacco bred difference, the height of growth is different, plant reserves blade difference, pinch highly different, at the knife rest of horizontal extension oil away from the hinged cutter sweep in one end of vertical lift oil cylinder, yoke plate one end is fixed on horizontal extension oil, the other end is provided with cutter sweep, cutter sweep is by hydraulic motor, disc cutter and angle electrical machinery composition, hydraulic motor output shaft is fixedly connected through the centre bore that disc cutter is arranged and disc cutter, hydraulic motor rotates and drives disc cutter to rotate, angle electrical machinery is fixed on knife rest, angle electrical machinery drives blade holder turns, regulate the angle between disc cutter face and horizontal line, disc cutter mounted in pairs, because tobacco epidermal tissue wood fibre is many, prevent the terminal bud of tobacco from can not thoroughly be cut off, swing on one side, double-arc spline cutting knife is two-sided to be cut simultaneously, the terminal bud of tobacco is positioned in the middle of two disc cutters, rotation direction is identical, if cutting knife is in same level, two cutting knifes must leave gap, not so talk about, cutting knife is interfered, damage the blade of cutting knife, cutting knife must with interlaced, cutting position is not in same level, as interlocking, be beneficial to cutting, terminal bud after cut-out is dished out by disc cutter, guarantee absolutely to pinch effect, not no marking, but do not damage tobacco blade and plant, the angle of two disc cutters is at 60 ~ 90 °, two angles are excessive, namely the angle between disc cutter face and horizontal line is little, disc cutter is near-horizontal state, blade near the terminal bud of Cutting free tobacco, the angle of two disc cutters is too small, namely the angle between disc cutter and horizontal line is large, disc cutter is near normal state, disc cutter is cut into a line, terminal bud cuts not thorough, in order to improve efficiency of pinching, two ends in the frame of tractor are installed two and are overlapped mechanism of pinching, one-stop operation two row, tractor is provided with control panel, be provided with operating key on the control panel, operating key controls vertical lift oil cylinder, horizontal telescoping oil cylinder, angle electrical machinery, the motion of the parts such as hydraulic motor, display screen monitors job state, horizontal telescoping oil cylinder is provided with video heads, the cut state of Real Time Observation disc cutter, because tobacco is in process of growth, blade upper punch, just as cat ear shape, the cutting knife of pinching must be obliquely installed, not damaged blade, only extract terminal bud, limit its longitudinal growth, regulate the distribution of nutrient, coordinate to nourish and grow and the relation of reproductive growth, adopt chemical control method weak effect, nourish and grow as adopted growth regulating inhibitor to suppress, have little effect, for the tobacco of nourishing and growing, usage amount is few, inoperative, usage amount is large, medicament residue, crop is vulnerable, contaminated environment, special tobacco is adopted to pinch equipment, tobacco plant distance and line-spacing density are greater than garden seedling tree, line space is little, line-spacing is generally at 50 centimetres, farm work complex, irrational state, tractor must be adopted as power, adhesive ability is strong, there is the traction power of coupling, and the equipment pruning general nursery stock must not be pinched as tobacco, as clipper, the function singlenesses such as arc pruning machine, overall structure is also not suitable for the use of pinching of tobacco, can not be simply alternative, disc cutter needs Nitrizing Treatment, improve hardness and rub proofness, keen edge, in addition, agricultural machinery selectivity is strong, special computer for special use, there is no versatility, agricultural machinery must not be replaced with graden machine, more there is no comparativity, some parts or even other equipment and this file more can not be taken to contrast, part can not replace entirety, same equipment is under different environments for use, the effect produced is different, distinct device still more, even identical parts, different combinations, produced result of use also different, any comparison will have comparativity, any machinery has its scope of application, have left its scope of application and there is no comparable meaning.

Compared with prior art, tool has the following advantages in the present invention.

1, tractor being arranged hydraulic pump drives vertical lift oil cylinder and horizontal telescoping oil cylinder to regulate its cutting position, two paired disc cutters due to tobacco epidermal tissue wood fibre many, prevent the terminal bud of tobacco from can not thoroughly be cut off, employing double-arc spline cutting knife is two-sided to be cut simultaneously, rotation direction is identical, interlaced, cut off and dished out by disc cutter, guarantee absolutely to pinch effect, not no marking, again not damaged blade and plant.

2, once can pinch two row, the speed of travel is fast, and save cost, efficiency is high.
